Question

One of the most feared predators in the ocean is the great white shark. Although it is known that the great white shark grows to a mean length of 21 feet, a marine biologist believes that great white sharks off the Bermuda coast grow much longer because of unusual feeding habits. To test this claim, researchers plan to capture a number of full-grown great white sharks off the Bermuda coast, measure them, and set them free. However, because capturing sharks is difficult, costly, and very dangerous, only three are sampled. Their lengths are 24, 20, and 22 feet. Do the data provide sufficient evidence to support the marine biologist's claim at α=.05?
